RESUMEN

BACKGROUND: While device-based circumcision is considered non-inferior to traditional dissection, there is no consensus on the efficacy and safety of ring devices in comparison with clamp devices. We aimed to compare the safety outcomes of ring-based versus clamp-based circumcision techniques in neonates. METHODS: MEDLINE, EMBASE, Scopus, and CINAHL were searched following the Cochrane collaboration (PRISMA guidelines), without language restrictions, to identify relevant randomized controlled trials. Adverse events, bleeding events, infection events, and procedure time were extracted and analyzed from the selected studies. RESULTS: From 1661 citations, seven trials were included, encompassing 3390 patients. These studies compared ring-based to clamp-based circumcision devices in neonates. No significant difference was found in overall adverse events between the two groups. However, ring devices showed significantly fewer bleeding events compared to clamp devices. Infection events and procedure time were similar for both groups. CONCLUSIONS: Both ring and clamp devices have similar safety profiles, with ring devices potentially offering a reduced risk of bleeding. A comprehensive understanding of ring-specific complications and cosmetic outcomes is necessary for a more complete evaluation of these circumcision techniques. Our analysis is limited from a lack of detailed examination of ring-specific complications and their impact on cosmetic results. The included studies varied in quality, and some exhibited a risk of bias. LEVEL OF EVIDENCE: Level IV Treatment Study.

RESUMEN

INTRODUCTION: Quality improvement (QI) efforts are critical to promoting health equity and mitigating disparities in healthcare outcomes. Equity-focused QI (EF-QI) interventions address the unique needs of equity-deserving groups and the root causes of disparities. This scoping review aims to identify themes from EF-QI interventions that improve the health of equity-deserving groups, to serve as a resource for researchers embarking on QI. METHODS: In adherence with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, several healthcare and medical databases were systematically searched from inception to December 2022. Primary studies that report results from EF-QI interventions in healthcare were included. Reviewers conducted screening and data extraction using Covidence. Inductive thematic analysis using NVivo identified key barriers to inform future EF-QI interventions. RESULTS: Of 5,330 titles and abstracts screened, 36 articles were eligible for inclusion. They reported on EF-QI interventions across eight medical disciplines: primary care, obstetrics, psychiatry, paediatrics, oncology, cardiology, neurology and respirology. The most common focus was racialised communities (15/36; 42%). Barriers to EF-QI interventions included those at the provider level (training and supervision, time constraints) and institution level (funding and partnerships, infrastructure). The last theme critical to EF-QI interventions is sustainability. Only six (17%) interventions actively involved patient partners. DISCUSSION: EF-QI interventions can be an effective tool for promoting health equity, but face numerous barriers to success. It is unclear whether the demonstrated barriers are intrinsic to the equity focus of the projects or can be generalised to all QI work. Researchers embarking on EF-QI work should engage patients, in addition to hospital and clinic leadership in the design process to secure funding and institutional support, improving sustainability. To the best of our knowledge, no review has synthesised the results of EF-QI interventions in healthcare. Further studies of EF-QI champions are required to better understand the barriers and how to overcome them.

RESUMEN

BACKGROUND: Biliary complications are common in pediatric liver transplant. Strictures resistant to interventional radiology procedures can be extremely challenging to manage and may result in the need of surgery or retransplantation. METHODS: This case report illustrates the use of biodegradable stents post left lateral segment live donor liver transplant in a pediatric patient with a recalcitrant chronic stricture of the biliary-enteric anastomosis. The patient developed a high stricture requiring multiple interventions and eventual access of both the segment II and segment III ducts of the graft. RESULTS: To ensure adequate biliary drainage, two biodegradable stents were deployed using a "kissing-stent" technique. The stents were successfully deployed and allowed the patient to remain free from an internal-external biliary drain for 11 months, with eventual redeployment of an additional biodegradable stent. CONCLUSION: In patients with recalcitrant stenosis of the biliary anastomosis, biodegradable stents may provide durable drainage, optimizing graft function and delaying retransplantation in addition to keeping patients without external devices, thus improving quality of life.

RESUMEN

BACKGROUND: A number of therapeutic treatment strategies exist for patients with hepatocellular carcinoma (HCC) and portal vein thrombosis (PVT). The aim of this review is to provide a current understanding of treatment options and determine the relative effectiveness of treatment options in preventing mortality over 24 months. METHODS: A search was conducted in PubMed, EMBASE and Cochrane CENTRAL from 2007 to 2022. Articles were screened to identify those that reported on all-cause mortality among treated, non-palliative patients with HCC and PVT. Study quality was assessed using the Cochrane Risk of Bias in Non-Randomized Studies of Interventions tool (ROBINS-1). Mortality rates at prespecified timepoints between 6 and 24 months were extracted and summarized using a random-effects DerSimonian-Laird model. This review was registered a priori on PROSPERO (CRD42022290708). RESULTS: When comparing radiotherapy (RT) to sorafenib and combined transarterial chemoembolization (TACE), there was a trend that RT yields better survival at 6 months [odds ratio (OR) 0.70, 95% confidence interval (CI): 0.28-1.76]. When comparing sorafenib to Y90 and RT, sorafenib was associated with higher odds for mortality at 6 months (OR 2.20, 95% CI: 1.11-4.39). No significant differences were noticed from 12 to 24 months. CONCLUSIONS: Future strategies for HCC with PVT should look at the combination of radiation and systemic treatments either concurrently or sequentially.

RESUMEN

Aim: The aim of this meta-regression was to assess the impact of mean/median age, mean/median tumor size, percentage of males in total sample, and total sample size on the comparative effectiveness of radiofrequency ablation (RFA) and stereotactic body radiation therapy (SBRT). Methods: Ten studies reporting on the composite outcome of overall survival and local control were included. Results: A significant relationship was found between age and overall survival at 1 and 2 for both RFA and SBRT. A significant relationship was noted also between age and local control at 1 and 2 years for RFA. Conclusion: Patients treated with SBRT had a wider range of tumor sizes and larger tumor sizes; no relationship was observed between tumor size and overall survival or local control by SBRT.

RESUMEN

Glioblastoma is one of the most aggressive types of cancer with success of therapy being hampered by the existence of treatment resistant populations of stem-like Tumour Initiating Cells (TICs) and poor blood-brain barrier drug penetration. Therapies capable of effectively targeting the TIC population are in high demand. Here, we synthesize spherical diketopyrrolopyrrole-based Conjugated Polymer Nanoparticles (CPNs) with an average diameter of 109 nm. CPNs were designed to include fluorescein-conjugated Hyaluronic Acid (HA), a ligand for the CD44 receptor present on one population of TICs. We demonstrate blood-brain barrier permeability of this system and concentration and cell cycle phase-dependent selective uptake of HA-CPNs in CD44 positive GBM-patient derived cultures. Interestingly, we found that uptake alone regulated the levels and signaling activity of the CD44 receptor, decreasing stemness, invasive properties and proliferation of the CD44-TIC populations in vitro and in a patient-derived xenograft zebrafish model. This work proposes a novel, CPN- based, and surface moiety-driven selective way of targeting of TIC populations in brain cancer.

RESUMEN

A new strategy for influencing the solid-state morphology of conjugated polymers was developed through physical blending with a low-molecular-weight branched polyethylene. This nontoxic and low-boiling-point additive was blended with a high-charge-mobility diketopyrrolopyrrole-based conjugated polymer, and a detailed investigation of the new blended materials was performed by various characterization tools, including X-ray diffraction, UV-vis spectroscopy, and atomic force microscopy. Interestingly, the branched additive was shown to reduce the crystallinity of the conjugated polymer while promoting aggregation and phase separation in the solid state. Upon thermal removal of the olefinic additive, the thin films maintained a lower crystallinity and aggregated morphology in comparison to a nonblended polymer. The semiconducting performance of the new branched polyethylene/conjugated polymer blends was also investigated in organic field-effect transistors, which showed a stable charge mobility of around 0.3 cm2 V-1 s-1 without thermal annealing, independent of the blending ratio. Furthermore, using the new polyethylene-based additive, the concentration of a conjugated polymer required for the fabrication of organic field-effect transistor devices was reduced down to 0.05 wt %, without affecting charge transport, which represents a significant improvement compared to usual concentrations used for solution deposition. Our results demonstrate that the physical blending of a conjugated polymer with nontoxic, low-molecular-weight branched polyethylene is a promising strategy for the modification and fine-tuning of the solid-state morphology of conjugated polymers without sacrificing their charge-transport properties, thus creating new opportunities for the large-scale processing of organic semiconductors.
